"Is Central Alaska the most similar type of geography to Finland in the United States? I would have thought Minnesota or Northern Maine."
I think the closest are Upper Peninsula of Michigan, Minnesota , Wisconsin.
"The topography, climate and woodland of this region are so similar to those of Finland that the transplanted Finn feels quite at home.
Mining and lumbering were the first occupations of the Finn after coming to this state."
